The answer to number 4 is 3850 and the answer to 5 is 975.
Math really can seem hopeless at times, can it? I can't recall the number of times that I've given up on math, but enough about me! There is a certain theorem in Geometry that states that the angle formed by two secant segments, 9x-5, is equal to half the difference between the intercepted arcs (64 and 158). I know this might sound extraterrestrial, but bear with me! Here is what it would look like in numerical form.
angle formed by secant segments = (1/2) (big intercepted arc - small intercepted arc)
(9x - 5) = (1/2)(158 - 64)
9x - 5 = (1/2)(94)
9x - 5 = 47
9x = 52
x = 52/9 or 5 7/9
Answer:Julios's number is 31
suppose: Julios's number is x
because Julio says, "If you subtract 13 from my number and multiply the difference by -3, the result is -54 "
=> we have: (x - 13).(-3) = -54
<=> x - 13 = (-54):(-3) = 18
<=> x = 18 + 13 = 31
<=> x = 31

Answer: Choice C, 2/3</h3>
============================================
Work Shown:
A = # of candies that are not green
A = (# of red)+(# of yellow)+(# of blue)
A = 25+15+20
A = 60
B = # of candies total
B = (# of red)+(# of green)+(# of yellow)+(# of blue)
B = 25+30+15+20
B = 90
P(not green) = probability of selecting candy that is not green
P(not green) = (# of candies not green)/(# of candies total)
P(not green) = A/B
P(not green) = 60/90
P(not green) = (2*30)/(3*30)
P(not green) = 2/3
